    "abstract": "We present a novel method for reducing the inhomogeneous frequency broadening\nin the hyperfine splitting of the ground state of optically trapped atoms. This\nreduction is achieved by the addition of a weak light field, spatially\nmode-matched with the trapping field and whose frequency is tuned in-between\nthe two hyperfine levels. We experimentally demonstrate the new scheme with Rb\n85 atoms, and report a 50-fold narrowing of the rf spectrum.",
